Belong to the program control technology field.

Background technology

Paying close attention to empty nest old man is the responsibility that we should use up, the old men are because a variety of causes, the situation of being in alone is a lot, meet accident if be in, and can not be succoured, the consequence that produces is that we are reluctant to see, is therefore urgent for empty nest old man design a kind of notifies with specific process the product that personnel outside go home.

Many see present present situation, existing a lot of devices, but all belong to some approximation functions have a long way to go with required requirement.Reason is as follows:

One class is when being in hospital, and a button is arranged on every sick bed, can touch the button when uncomfortable, and notice nurse job point is in the hope of looking after.Obvious this mode is not suitable for family, because empty nest old man's relatives or volunteer can't implement usually in the place away from him at all.Close to otherwise during because be in hospital, patient puts from the nurse, and the nurse is that specialty is waiting for, so available wired form is contacted directly.

One series products is that the telephone alarm of selling on market is sold, and this product is when in family, the robber being arranged, to notify the household, and the advantage of this product is to have used telephony platform, if but be used for situation required for the present invention with this product, also there are serious problems.The one, in family, the old man meets accident and how to open machine, and the 2nd, it is the Advise By Wire device after a speciogenesis burglary, the design of its function and requirement difference therewith is very large, can't substitute.

One class situation is present 3G mobile, these facility have call performance more easily, are a kind of good selections, but not enough be that mobile phone is must button many, to feel " science illiteracy " to some old man one, the 2nd, can not accomplish repeatedly calling out automatically multimachine after once-through operation.The 3rd, during accident, the simplification of operation is not accomplished in operation, because of rather than most convenient.

Due to above reason, so seriously lowered the relief dynamics.

This is external also has following difficult point when the present invention is developed:

Is in the mode of transmission of information, the best way to use phone, but when meeting accident, the old man may have set a distance from telephone set, so what kind of mode of the old men could be opened and takes on the telephone? will and put through the numeral of multidigit? how could take and to do the microphone conversation.If use remote control mode, but now the remote control product is more and more, and interference source also increases, and just signal can accurately be sent and without the interference of current collector, this is also a difficult problem with which type of coding.

Any good electronic product all needs a kind of stabilized voltage power supply preferably supporting with it, if but present circuit of three-terminal voltage-stabilizing integrated without transformation directly application can not reach effect preferably.Its main cause one is that the lightning protection grade is not high, and the equipment of ensuring public security like this will may damage at thunderstorm season, or cisco unity malfunction, will cause the protector serious period out of control.The 2nd, can not work in the very wide scope of civil power, directly affected the range of application of security personnel's equipment.The 3rd, voltage stabilizing numerical value can not be transferred to the voltage stabilizing value of decimal neatly, as 3.7 volts, and 12.7 volts.Cause a major reason of above 3 deficiencies to be that the inherency of the three end integrated stable voltage circuits (as circuit of three-terminal voltage-stabilizing integrated 78 series) in electronic product causes, the voltage of 78 serial integrated regulator inputs can not be too high, is generally 30 volts.And have the input of three end integrated circuits when being struck by lightning to surpass this value.So caused the deficiency of first aspect.Cause the reason of the deficiency of second aspect to be, also because the input voltage rated value of three ends is not high, so the design of the secondary low-voltage side output voltage of transformer is restricted.in present traditional design, although proposed the scheme of triode and three end co-design, but produced again new contradiction, owing to having increased easy failed part voltage stabilizing didoe, this just may produce the negative sense result of two aspects, the one, reliability is affected, the 2nd, lightning protection effect is affected, cause the reason of the third aspect to be, because the output valve of circuit of three-terminal voltage-stabilizing integrated is a certain integer value of fixing, as, 5 volts, 8 volts, 12 volts, can't the satisfy the demand float charge voltage of fractional value, as 12.6 volts, Deng, also inconvenient when adjusting its voltage stabilizing value, namely be unfavorable for batch production.The stabilized voltage power supply of joining also relates to many-sided constraints such as cost and reliability, so required stabilized voltage power supply is simple at first sight, but carefully analyzes, and but many places difficult point abrim, also further innovation, this is again a difficult point.

So also need at present exploitation and enrich this series products, for the old men provide the sense of security, enjoying the old age of happiness.

7, in the Advise By Wire device lead-in wire mode of phone be first with wire bonds on weld tabs, weld tabs sticks on phone keypad printed panel Copper Foil again.

Be the clear meaning of understanding the technical program, at first will make the following instructions:

﹠lt, b TranNum="87" ﹠gt, ﹠lt, / b ﹠gt, in the common communication telephones in market, generally all have a number storage function, the telephone number that is with often puts through of the argument of this function of telephone set design is easy to use, its reason be if will often dial the number in advance be stored in storage key in telephone set after, when putting through ordinary phone, a plurality of keys should be dialled and the mode of the code of long number could be transferred to, become and only press the simple and direct form that a key just can be transferred to the multidigit number, thereby use very convenient, because such characteristic is arranged, thereby created important prerequisite for the invention process measure one, the present invention utilizes this characteristic exactly, in advance in phone, stored kith and kin's number, when accident is arranged, the old men can the operating and remote controlling box, after receiving element is received signal, rise and employ program unit, replace traditional manual dial's mode with it.

The meaning of abovementioned technology, concrete condition further is explained as follows:

1, the wireless remotecontrol radiating portion is to be carried by the old men in principle, is mainly in case unexpected.Meeting accident, they only need to click the simple motion of button just can launch, and due to simple to operate, more can not produce " science illiteracy ", thereby can start the love advising process with the simplest mode.

Implemented the wireless remote control emission and adopt or gate-type multi-code transmitter scheme in technical scheme 1, important meaning is arranged, main benefit is to be difficult for producing malfunction.Use now the apparatus of remote control many, as locking that car door is protected, with release etc., all want straighforward operation, just formed possible interference source.If something unexpected happened at home for the old men, can not receive timely because of increasing of interference source and rescue signal, consequence is very serious.And adopt the many yards artificial disturbances that just can thoroughly stop afterwards this class.This circuit realizes that the principle of multi-code transmitter is; When the first end output of emission programme control circut was high-order, it was low that the inverter output that connects makes the chip select of this coding integrated circuit of connected, this chip select work of institute, and remaining sheet is not worked.Be output as when high when second, in like manner only have corresponding section's chip select work.Due to each coding integrated circuit with or a door mode be input to modulating tube, so form the form of multi-code transmitter.

2, in technical scheme of the present invention, except having adopted the Advise By Wire device, also have two kinds of electronic circuits in telephone set.A kind of is the radio reception circuit, and it can transmit from the wireless remotecontrol that the user sends by reliable reception; Another kind of part is a kind of reception programme control circut, and it has connected 5 groups of lead-out wires of drawing from telephone key rosette copper paper tinsel, the number of storing in telephone set is transferred to successively.

In telephone set, radio reception circuit Main Function is the starting point that control to receive programme control circut, that is to say the old man with the signal that sends of reflector, in a single day receiver receives signal, just can send instruction, allows receive programme control circut and start and start working.The function of order circuit is stored telephone set moves successively except allowing, and can regularly stop simultaneously.Its connotation is, to no longer opening all and store keys after close the telephone set Hands-free key certain the time, will realize the shutdown of telephone set and the automatic stop of whole control system.

3, this telephone set by the such reforming processing of telephone set process, do not relate to communication part, so still can be used as the communication telephones use at ordinary times.

4, box is as follows by emission and acoustics circuit reason dimerous with oneself:

The one, because carry-on box is to be with oneself, so when accident is arranged, or the old men and telephone set have apart from the time, can operating and remote controlling box replacement manual dial.

The 2nd, because people when the accident may have distance with telephone set, can't take receiver that telephone set is joined, but this moment is because receive programme control circut unit starting, telephone set is in hands-free operating state, thus can give orders or instructions without receiver, and with oneself box has increased behind the audio amplification circuit unit telephone set that pass to again hands-free operating state after can meaning epigenesist sound amplifying, improved the effect of hands-free work, therefore the less sound of that fearness of the old men, after amplifying, can obtain effect preferably.

5, sound equipment of the present invention amplifies side circuit, and element is little, rings wide ranges frequently, gain high, and adjustable flexibly, also very convenient in being arranged on carry-on box, the 1st step of this integrated circuit and the resistance between the 8th pin and capacitances in series part can be adjusted the gain size.

Can solve well when meeting accident the dialing of people's DR telephone machine and the contradiction of taking receiver so coordinate with main body of the present invention with carry-on box.

6, adopt relay as telephone set lead-in wire and the interface circuit that receives programme control circut, following benefit to be arranged:

When the reception programme control circut was not worked, because relay contact is in normally open, the lead-out wire of telephone set did not produce any negative interaction to telephone set, and telephone set can normal talking.And when receiving programme control circut work, telephone set is produced correct logic.

7, modular power supply has important meaning in the present invention, and this circuit spy is made the following instructions:

(1), circuit totally consists of and main feature: adopted traditional three end integrated circuits to make the last output of voltage stabilizing.Before three end integrated circuit inputs, increased the one-level emitter follower and made buffer, but the design one different from tradition is not contain consumable accessory zener diode, good reliability during this grade normal operation.The 2nd, thunderbolt (overvoltage) there are three grades of strick precautions, overvoltage is taken precautions against effective.The 3rd, adopted 3 measures to make three adjustable, the easy accent of end integrated circuit voltage stabilizing value.

(2), the explanation of three-level protective principle has been carried out in lightning protection.One of be to have increased emitter follower newly between rectification and three end integrated circuits, high back-pressure high power valve is adopted in this pipe design, its back-pressure can reach hundreds of volts, is almost 10 times of left and right of the circuit of three-terminal voltage-stabilizing integrated input voltage of 78 series, is equivalent to ability to bear and has improved 10 times.Two be to have increased anti-thunder tube to make second class protection, the limiting voltage in the time of can be with thunderbolt is in the scope of tens of volts of puncture voltage.Three be to have increased " lightning protection overvoltage backup " circuit in the base stage that output voltage is adjusted pipe, (voltage-stabiliser tube 327 branch roads in Fig. 1), the operating state of this pipe is, be at ordinary times the no current conducting state, its reason is that in circuit, selected voltage-stabiliser tube voltage stabilizing value has surpassed the pressure drop of two resistance series arms (328 in Fig. 1 and 329 series arms) over the ground of emitter follower base stage, so by clamper.Formed like this benefit of two aspects, the one, no current during because of usual work does not produce electrical wear, so can not damage, has guaranteed reliable when using.The 2nd, when input has high pressure; as thunderbolt; or the civil power accident is when having high pressure; 328 and 329 series arm pressure drops in accompanying drawing 1 raise; at this moment " lightning protection overvoltage backup " branch road, (voltage-stabiliser tube 327 branch roads in Fig. 1), conducting immediately automatically; newly-increased emitter follower base stage is produced pressure-limiting function immediately, implement protection.Due to the three-level protective that has formed thunderbolt, so when bad weather, needn't be to the disconnected power down of the present invention source, and can work.

(3), can not damage the circuit explanation in civil power higher place and period.Its reason such as back and forward, thunderbolt are a kind of reasons of overvoltage.The lightning protection circuit effect is adapted to civil power unexpected the time too.

(4), can be in the explanation of the lower place of civil power and period work.Newly-increased emitter follower is high inverse-voltage tube, so the secondary low-voltage output end voltage of transformer can design higherly, when civil power is low, rectification output is had compensation like this.Therefore expanded the civil power lower range.

(5), can expand the explanation of civil power excursion.Its reason is that civil power does not damage circuit when high, and when low, compensation is arranged, so expanded the operation interval that civil power changes.

(6), take the adjustable and easy Several Measures of transferring of three-terminal voltage-stabilizing value.One of, being designed with three ends and adjusting the adjustable peripheral circuits of voltage stabilizing value, this circuit is by in Fig. 1: 333,334,335 3 elements form.Two, three end integrated circuit earth terminals and ground wire between adopted the mode of the branch road that diode connects with resistance, solve easily batch production and adjust flexibly the contradiction of voltage.Due to three end integrated circuit models and individual difference, the electric current that earth terminal flows out is variant, if only is connected with resistance between its earth terminal and ground connection, the resistance of similar resistance is not easy to produce the consistency of pressure drop, is difficult for producing in batches.Can address this problem with diode, only the electric current of pipe inflow diode has the difference of size, and its pressure drop is 0.7 volt, so batch production need not be adjusted.If but this branch road is only used diode, but can not adjust flexibly required voltage stabilizing fractional value, so the present invention has adopted the adjustment branch road of both series connection, in this branch road, diode is coarse adjustment, because being the major part of pressure drop; And the pressure drop of institute's crosstalk resistance is minute portions, is accurate adjustment.Three, increase by one road branch road (333 Fig. 1) from three ends outputs in adjustable peripheral element, to strengthen easy batch production.Due to the electric current of this branch road, occupy larger specific gravity in diode and resistance series arm, beneficial to overcoming three end integrated circuit models and individual difference, be conducive to batch production.The rule of adjusting the three-terminal voltage-stabilizing value is, in Fig. 1, resistance 334, and resistance is higher, and output voltage is higher, otherwise lower.

(7), in the present invention, in the peripheral element of newly-increased emitter follower, cancel the meaning of the voltage stabilizing didoe in the main thoroughfare and form principle.In traditional design, with triode and three end co-design, all need to the base stage of emitter follower over the ground branch road add voltage stabilizing didoe, and this voltage-stabiliser tube is the main branch road of switching on for a long time.Within its objective is that only in this way this pipe output of guarantee can be controlled at rated range.Electronics staff with batch production all knows, voltage stabilizing didoe is a kind of easy failed part, particularly is used in the power supply local (voltage-stabiliser tube 327 is to be in long-term "on" position) of long-term energising.For avoiding this problem, the present invention has adopted to be difficult for failed part resistance unit replacement easy-to-damage element voltage stabilizing didoe, the principle that forms is, newly-increased emitter follower base is pressed Circuit tuning, when normal operation (be namely groundwork path) is 328 and 329 series arm in Fig. 1, rather than " lightning protection overvoltage backup " branch road, not namely 327 voltage-stabiliser tube branch road in Fig. 1 yet.Because this branch road voltage stabilizing value is higher than 328 and 329 series arm pressure drop, during normal operation, by clamper, no current only has accidental cause to wait the overvoltage reason as thunderbolt, and in figure, voltage-stabiliser tube 327 just has electric current to pass through.What also should illustrate simultaneously one is, in the design of the series arm 328 and 329, the pressure drop of resistance 329 is main, be essentially three end output voltages, (only differing from a PN joint), and when design, pressure drop on adjusting resistance 328 only has the three ten-day period of hot season, just can guarantee that the emitter follower output voltage satisfies the input voltage of three end integrated circuits, because this circuit output essence is surely three end integrated circuits, so its voltage regulation performance can not be affected.The 2nd,, because the pressure drop on resistance 329 is mainly that output current by three end integrated circuits provides, rather than by on the emitter follower base stage partially resistance 326 provide, so track stability and easy tonality are played great role.

(8), improve the Several Measures of reliability: one of, in lightning protection circuit, formed three-level protective, (seeing second).Two, the buffer base presses Circuit tuning to be comprised of resistance series arm (328 and 329 series arms in Fig. 1); do not contain easy failed part voltage stabilizing didoe, not fragile, three; design " special substitutes " protected mode branch road in the protection of the lightning protection third level, further improved reliability.

After the invention process, following outstanding advantage is arranged:

1, meet accident as the old man, and can't normally go to when calling before phone, the old man can be by the launch-box button of carrying, the love advising process of starting telephone set, allow and go home to visit away from oneself relatives, and the addressee can adopt base, also can receive signal with mobile phone, due to portable mobile phone, so no matter the addressee is on duty or not closes outside and all can receive.

2, compare with mobile phone, use simplyr, the call dynamics is much bigger.Because need to rout up cell-phone number with mobile phone, need to determine, need a plurality of buttons of operation, for " science illiteracy ", or undynamic old man, can be unable to do what one wishes.And bright of basis gets final product by a button, and can call out simultaneously the multi-section phone when calling out.When meeting accident, if the old men away from telephone set, after putting through telephone set, although can not use earphone that phone is joined, because carry-on box is furnished with amplifying circuit, still can conveniently converse with the other side by hand-free function.

3, the present invention adjusts flexibly, can store relatives friend's phone, also can store the phone of hospital 120, if what store is latter's signal, after the present invention's starting, can allow the other side know that the relevant informations such as address or characteristic of disease race against time by voice sheet.

4, function is excellent.Embody in the following areas, the firstth, no matter local far and near relatives are, and he can receive call signal by the network platform.The secondth, the mode that the user adopts is called out the advanced person, in the situation that only pressed button No. one time, or during accidental falls, all may start the love program, and program will be carried out automatically later on, and the user no longer operates.The 3rd is to be two phone signals automatically transfering and stored in calling procedure, and sends in an alternating manner, if wherein a phone is not started shooting, another phone can receive.The 4th is to be that two hands alternately and are repeatedly called out in calling procedure, if in this is called out, the situation that the line is busy is arranged, also can receive in calling afterwards.The 5th be the other side after connection, both sides can converse, because what be at this moment that phone opens is hands-free, can certain distance be arranged with phone.

5, simple and easy to use, only need press the button of launch-box once just, is all just automation later on, will not produce " science illiteracy ", the simplification that has realized operating.

6, anti-unexpected good, the one, launch-box is small and light, can carry, the 2nd, just one of launch-box can be joined a plurality ofly, also can place in the room more, and safety factor is large.

7, after the invention process, telephone set still has all communication functions of phone, and a tractor serves several purposes does not increase ornaments and the apparatus of family, does not affect life and the custom of family, and family does not have too much ornaments and affects attractive in appearance.

8, be easy to produce, because utilizing a lot of circuit compositions in telephone set, relatively simple.

9, the audio amplification circuit element of launch-box is few, effective.

10, modular power supply used is as the power supply of receiving circuit, its benefit have following some: (1), performance are good, embody in the following areas: the one, anti-thunder is effective; has the lightning protection three-level protective; at thunderstorm season, not fragile, supporting electrical equipment needn't quit work at thundery sky.The 2nd, adapt to widely, than traditional stabilized voltage power supply, wider adaptive capacity is arranged, be namely that the protector of joining work when the high place of voltage and period or accidental cause can not damaged, and also can work in voltage lower place and period.The 3rd,, can be used for exporting the voltage stabilizing value that there is decimal in generation.And the existing achievement of inventor is security personnel's classes, need to be to the floating charge circuit of storage battery, and this circuit can not be integer value.So the present invention has very strong ability to provide the auxiliary items, the 4th,, excellent performance.

(2), reliable.Reason one is that in electronic circuit, voltage stabilizing didoe is also one of easy failed part, and in the present invention, voltage-stabiliser tube has been done special processing, so reliability is higher than traditional co-design.Reason two is, newly-increased emitter follower Guan Weigao back-pressure high power valve in the present invention, and reliability generally all is much higher than common triode.
